The COVID-19 pandemic has changed education. In these circumstances, technology aided learning by providing new ways of teaching and communicating with students. In this work, we report the online activities carried out in the Basic Organic Chemistry virtual course of the Chemistry Department at UNS (Argentina) for first-year students of the Agronomic Engineering career. In particular, we present the use and results obtained from quick question/answer games using available applications to reinforce theoretical concepts. These activities helped to review and emphasize essential concepts of the course. It is noteworthy that the proposed activities also supported learning during the return to face-to-face classes.
